Figure 1. Graphical representation of Linkage Groups I and O based on the soybean composite map at www.soybase.org (verified 13 Dec. 2006). The BACs gmw1-15k6 (FAD2-1A) and gmw1-105h23 (FAD2-1B) mapped to these linkage groups in the Glycine max A81-356022 x Glycine soja PI 468.916 mapping populations. Their locations relative to other markers are shown. Lines between markers show syntenic markers.
